To all whom it may concern Be it known that I, WILLIAM BALLAN- ruin, asubject of the King of. Great. Britain, and a resident of'the town ofMission. City, in the Province of British Columbia-{Canada, haveinvented certain new and useful Improvements in Stump-Pullers, ofwhichthe following is a specification.

My invention relates to improvements in stump pullers, andlt'he objectofmy invention is to devise a machine of this character which, while beinglight and compact,

is of great power, and which is easily transported from place to placeand capable of being operated by one man with great ease,

rapidity and continuity of operation.

I attain this object by the construction illustrated in the accompanyingdrawings in which- V Figure 1 is aside elevation of the machine. Fig. 2is a plan view. Z Fig. 3 is a-view illustrating the operation of theinvention.

Similar figures of referenceindicat'e simi- 5 lar parts throughout. theseveral views.

1 indicates generally the frame of the machine formed of the two sidemembers 2 and i 3 connected together at their forward ends by atransverse member 4 provided at midlength with an eyebolt 5 while to therear ends of themembers 2 and 3 handles and 7 are pivot'ally connectedas ind cated at 8 in Fig. 2. the free ends of the handles being formedhooleshaped, as at-9 and 10 so that an anchor rope, indicated by thenumeral 11 in Fig. 3, may be attached thereto, as hereinafter described.The handles 6 and 7 are maintained in any plvotallv ad usted position bymeans of stay rods 12' one end of each of which engages, lts respectivehandle while the other end s adapted-to en age one. of a series of holes13 prov ded in a transverse member 14' connecting the rear ends of themembers 2 and. 3.722s shown in Fig. 2. The frame 1 is mounted at its formeshes with a large pinion 19' secured to a transverse shaft 20rotatably' mounted on the frame and on which shaft to one side of thedrum gear 18 is secured another large gear 21 meshing with a pinion 22secured to a transverse shaft 23 rotatably andslidably mounted invertical brackets 24 and 25 secured to the side members 2 and 3, thisshaft 23 being also provided with a rigidly securedratchet wheel 26 withwhich coho" eratesa pawl 27 carried by a handle 28 swingably mounted onthe shaft 23,'the op- 1 eration ofwhich handle in arearward di rectionrotates the wheel 26 and shaft 23. backward movement of the wheel' 2 6being prevented by means of a "suitably mounted 7 pawl 29' inspring-pressed engagement with the teeth of a wheel secured on the shaft23 outsideof bracket 24 while the slidable movement transversely of theshaft to dis engage the pinion 22 from gear 21 when not required islimited b means of a collar 31" secured thereonf When the pinion'22and'gear 21- are in use', however, the shaft 23 is kept from'transyersemovement by" means of a cap 38 which is secured to bracket 25 andwhich-may be swun'g' up to permit transverse movement oftheshaft whendisengaging the pinion 22. The ends of the drum shaft. and ofshafts 20and-2 3. are squared so that a. su table operating handle may be placedon them as required? 1 The manner in which. the m"chine" is op- .eratedmay be brieflv' described as follows:

For small and medium si ed stumps'the rear anchorageis a-llthatisre'ouired.',thi.s

being obtained by passing the rope 1 1 around a stum 32,.asin'dicated inFig. 3] the: pulling'cable be ng then simply attached to the stump to bepulled and to the drum. while! for large stumpsa block 33attachedf as achoker 3401i the tump 35 to be pulled may be used, the ul ing.cableZ-Jti inlthat case passing throu h the reassessedbeingpro:

titled with a hook 37 adapted to engage in the eye bolt 5 By thearrangement of gearsshown in Figs. 1 and 2, that i high the strain islight the speed is great due to the operation of the drum 'by rotationof the handle directly mounted on" the drum shaft. As the strainincreases the handleis' placed on the shaft and the pinion l9 rotated,thus lessening the speed to'take the heavy strain until the tension isgreat enough to require theuse of the ratchet 26 to operate gear 22,;orthe low gear, until the heavy part ofthe {full is over, when the speedmay be again increased by changing back from'low to ;medium and frommedium to high gear as when starting the operation, the whole processbeingsimply first from high gear to medium gear, from medium'gear to.low, gear, from low gear *to medium,and finally from medium gear a tohigh gear, thus leaving the machine ready for the next stump withoutfurther adjustment. From the foregoing it will belseen that I 4 havedevised a simple and "easily operated frame,laterallyadjustable grippinghandles stump puller which possesses great power compact, and readily 7while being light, transportable, p What I claim asmy invention 1s 1Y 1. A stump PIlllBIQCOIDPIlSlIlg a wheeled at the rear of said framewhereby the same maybe wheeled, means for securing the handles inadjusted position, a drum' rotajtably mounted on the frame, andmechanismassociated with sald drum forrotating it at different speeds.

2. A stump puller comprising, a wheeled frame, gripping handles-at therear of said frame whereby the same may be wheeled,

said handles being pivotally connected so as'to be capable of beingspread laterally frame whereby the same may be wheeled, said'handlesbeing pivotally connected so as a at their free ends, a drum rotatablymounted on the frame, and mechanism associated with said drum forrotating it' at different speeds.

3. A stump frame, gripping handles at the rear of said to be capable ofbeing spreadclaterally at their free ends, means for maintaining saidhandles in any adjusted position, a drum rotatably mounted on the frame,and mechanism associated with said-drum for rotat- 7 ing it at differentspeeds.

4. A stump puller comprising a wheeled frame, gripping handles'pivotally connected puller comprising a wheeled July, 1919.

at one end to the rear of said frame and hook shaped at their free endsso that an anchor rope may be attached thereto, a drum rotatablymountedon the frame, and mechanism associated with said drum for "rotating itat different speeds.

A stump puller comprising a wheeled frame, gripping handles pivotallyconnected to the rear end of said frame for wheeling "it, said handlesbeing hook shaped at their free ends, a drum rotatably mounted adjacentthe forward end of the frame provided 'with a gear, a manually operabletransverse shaft rotatably mounted to the rear'of said drum providedwith a pinion rotatably mounted above the frame pro vided with pinion,sald shaft being laterally. slidable to carry said pinion into or outofengagement withsaid large gear, and a pawl and'ratchet mechanismmounted on said shaft I for operating it.

6. A stump puller comprising'a rectangularc frame mounted at its forwardend on. wheels and having supporting legs at its" rear end, said framehaving transverse members at its forward and rear ends, the forwardmember being provided with an eyed member and the rear one with a seriesof holes, gripping handles pivotally connected to the rear end of saidframe for wheeling it, said handles being capable of being spreadlaterally and formed hook shaped at their free ends and having staymeshing'with the drum gear and also pro vided with a large gear, atransverse shaft use shaft being laterally slidable to carry said pinioninto or out of engagement with said large a pawl and ratchet mechanismmounted on said shaft for operating it in a forward direction, and meansfor holding said shaft against inadvertent backwardmovement.
